This week began with the luxury of an extra hour as the clocks went back so I spent a little of my longer Sunday morning in a leisurely wander around my dew soaked garden. Mist hanging in the valley is always promising and as it drifted off down the river valley to evaporate and disappear, our level of the hillside poked up out of it, the sun reached us and the garden glowed.
The morning light of autumn has a warmth to it which belies the air temperature, but I was still surprised that the wild honey bees, which came of their own accord this spring to an old hive in a shrubby corner of the garden, should be so taken in by it. They were as busy as on any warm summer’s day, the baskets on their hairy little legs bulging with pale pollen.
Not far away from here is a very ornamental garden, its keen owner grows bouquets full of late season exotic flowers and as the weird weather exacerbates the phenological mismatch caused by climate change, I have splashed out on a few plants of different Echinacea, Aster and Rudbeckia species. They all flower into autumn and should, I hope, extend the availability of forage for both the honey bees and importantly the species of native bees and other insects still flying.
The ivy flowers appear to be stripped bare now and the dead headed Buddleja are long over, but Geranium ‘Rozanne’ is still going strong, as is an unnamed Persicaria amplexicaulis. Originally one large and long flowering clump, I have split and re-split it into dozens of smaller pieces which now live all around the garden, growing away and gathering steam to feed generations of bees and wasps to come.
As the perennial flowers give up the ghost, their seed heads will remain to decorate our winter and provide cosy homes for unknown and unnamed tiny creatures. Next to flower will be Mahonia, beloved by queen bumble bees it has the heady and unseasonal scent of lily of the valley, and as we wait into winter the for hellebores to flower, Viburnum tinus fills the gap.
I’ve never seen insects on mine, which logically must be as much to do with cold weather and lack of insects as the viburnum’s food value. Beelife.org tells me that they are full of pollen and nectar and although Gardeners World disagrees, I shall keep a look out this year especially in mild spells.
These plants have all been deemed to be ‘garden worthy’ but none of them are native to us. There are people who would deny them their place in a wild garden for that reason, but as I watch the feral honey bees coming back to their hive, I can see how active they still are and how much they need the food they’re finding in those flowers which evolved with other insects in other ecosystems far from ours.
To all the insects still flying and the spiders, hedgehogs and birds which they in turn feed, any flowers still providing sustenance are valuable, so as my garden’s human ecosystem engineer I shall carry out some disturbance by putting in my new plants, dispersing them around the garden and in doing so add a little more diversity.
The time to be purist is long gone, biodiversity loss continues apace, it really is a matter of life or death, and not just for the late flying insects.
Note. Phenological mismatch is the way interacting species are changing the phases of their life cycles at different rates.
